Abstract: A lithium-ion battery that includes a plurality of electrodes, such as an anode and cathode, and at least one of the plurality of electrodes is made of a conductive material having a single wall Fullerene-carbon nanotube additive. The use of single wall carbon nanotubes as an additive in the electrode materials, even in very small amounts, improves the capacity, thermal stability, and safety of the electrode materials.

Abstract: A lithium-ion battery having at least an anode that includes phenol formaldehyde in a range of 0.1% to 10% by weight as a binder material. The phenol formaldehyde, or a mixture of phenol formaldehyde with polyvinylidene fluoride (PVDF), is used as a binding material in a Li-ion battery negative electrode to decrease the exothermic reaction of the battery during charging and discharging, which accordingly lessens the risk of thermal runaway and rupture of the battery.

Abstract: A method for making a coated electrode material for a lithium rechargeable electrochemical cell (10) includes the steps of mixing (65) Co and Li salts, then either dissolving (70) the Li and Co salts in water to form a solution or heating (70) the salts to form a melt. A lithium nickel oxide material is mixed (80) with the solution or the melt to form a mixture, and the mixture is dried (85) to result in LiCoO.sub.2 -coated LiNiO.sub.2. Increased performance can be achieved by including a post-treatment step in which the LiCoO.sub.2 -coated LiNiO.sub.2 is heated (90) to about 700.degree. C.
